Hebe, my friend, we also say parrandero here in Cuba but it is more referring to popular parties, like a massive carnival thing. I would definetely go for fiestero, seems like we all use it in our countries.

I agree SandraT.

In Argentina we call "farandula" to the famous media people (actors, actresses, etc.) and we say "se fue de parranda" more than "parrandero".... "no estaba muerto, estaba de parranda..." says the song.
